Head-mounted display

A head-mounted display including a device body, an assembly and a projection device is disclosed. The assembly includes a reflective surface, and is pivoted on the device body. The projection device includes a liquid crystal lens element, and is disposed inside the device body. The projection device is used to project an image beam on the assembly, and the assembly reflects the image beam to a projection target. The projection device uses the liquid crystal lens element to calibrate an aberration generated from the reflective surface of the assembly. Through the liquid crystal lens element and the optically adjustable characteristic thereof, the head-mounted display has good display quality and has the effects of increasing convenience and flexibility in use.
